TLUG,

Yesterday, I one of the machines on my home network upgraded the kernel
to 2.6.32-24-generic.

Today, I can't connect to it by NFS.  Usually all the computers hook up
when I boot.

When I try to run a mount -a command, I get this error:

mount.nfs: mount to NFS server '192.168.0.4:/home/media' failed: RPC
Error: Program not registered

Any idea how I can troubleshoot this?

If you run 'showmount' on the server what is it's output? This should show a list of machines that are allowed to mount local directories.

If you run 'showmount -e <server_ip_address>' from the client what is it's output? This should show you the list of shares the nfs server has and the allowed hosts to those shares.

Also, aside from the error you get when you try to mount the share are you getting any errors in your log files? Are you using tcpwrappers (/etc/hosts.allow, /etc/hosts.deny) to protect the system, after a bit of googling it seems some people have fixed similiar issues by readjusting tcpwrapper config a bit.
